hawk2eye said:?? How can I adjust a home made 36.0 kHz RC-5 Infra_Red remote so that it will operate a IR receiver + PIC 16F84 ??
1. NO oscilloscope is available !
2. Can an LM555 oscillator be built using 1% Resistors and Capacitor ,
so that with less than 5%error ?

hawk2eye said:Question:
Do you mean to calculate the timing for using a PIC as an oscillator
to provide the RC-5 circuitry:
both the Manchester (bi-phase) commands +36 khz IR carrier?
DigiTan said:I noticed a lot of IR devices and IR receiver modules also have a fairly wide passband centered somewhere around 36kHz, so your timing doesn't have to be perfect. If your PIC has an internal timer/counter with a wide variety of prescales, that really helps.
DigiTan said:I guess it all depends on the throughput. Having it interrupt-controlled on a fast µcontroller could let you squeeze in a few outside instructions in between IR carrier edges. Otherwise, nop works just as well.
